Description
Summary:This paper presents the results of a passive optical lightning sensor for utilities applications. The main sensor application is for the location of lightning strikes in overhead power lines, but it can also be used in substations or in power generation plants. The proposed sensor detects lightning indirectly by means of detecting lightning electromagnetic pulses, which are used to modulate directly a semiconductor laser coupled to a fibre optic pigtail. No solar panels, batteries or electronic control circuits are necessary to implement this sensing technique. This paper shows the results of the sensor characterization made only in laboratory and the possibilities of its use in an optical WDM sensor network.
